From the reviews
We've been at One for a year and a half and love it. The Professors are encouraging and patient. No one in our family did a contact sport prior to starting Jiujitsu, so our learning curve is steep. The higher belts here are also so kind. This place has a very inclusive and inspiring culture.
When you walk onto this gym youll notice the beautiful white ascetic it gorgeous. When I travel I always see which gym are near by so when i saw One jiu-jitsu was nearby I reached out to see if I could drop in while in town . the teaching js great and the atmosphere is very fun and cool.
My son started training under Giva 4 years ago when he was 10 years old. He participated in the kids class I myself joined 2 years later when I could not resist the temptation to train and learn from one of the best jiu Jitsu professionals in the world. My son loved going to the kids class.
This place is amazing. As a former Army combatives instructor, and former law enforcement, I wanted somewhere for my 5 year old daughter to learn jiu-jitsu. I am so glad we found ONE jiu-jitsu.
New to BJJ? Start at One Jiu Jitsu
One Jiu Jitsu comes up as a beginner-friendly gym, going by their listing and members’ reviews. If you've never rolled or set foot on a mat, that's exactly who a good beginners program is for. A few things worth knowing before your first week. First, you don't need to be fit or flexible to start — you get in shape by training, not before it, and coaches scale the intensity to you. Second, you won't be thrown into hard rolling — reputable gyms build fundamentals (positions, escapes, and basic submissions) for weeks, live rolling eases in gradually, and tapping early keeps every roll safe. Third, all levels really are welcome — ask about a dedicated beginners or fundamentals class time so your first session is alongside others who are also starting out, and leave your ego at the door. Most gyms are happy to let you watch or try a class first, so reach out before you commit.
Your first BJJ class at One Jiu Jitsu
Nervous about walking into a BJJ gym for the first time? Almost everyone is, and good coaches expect beginners to come through the door. Here's what to know. What to expect: a typical first class is a warm-up, then drilling basic positions and escapes with a partner — not hard sparring. Rest whenever you need to; no one will bat an eye. What to wear: athletic wear you can move in (or a gi if you have one); you'll train barefoot on the mats. What to bring: water and a mouthguard if you have one — many gyms lend a loaner gi for a first class, so it's worth asking when you call. As you keep training you'll add your own gi (or a rashguard and shorts for no-gi) and a mouthguard. Live rolling eases in gradually, once your fundamentals are solid. Arrive 10–15 minutes early to sign a waiver and meet the coach. It gets easier fast — most people feel far more at home by their third class.
